Gijinka Anthropomorphism, personification. This can refer to simply attributing human characteristics such as speech to animals or inanimate objects, which can be done just in life, or advertising, or whatever, but more specifically might be done in fiction, particularly anime or manga. It can also refer to art (whether official or fan art) in which animals or objects are given at least partially human appearances (or humans can be given at least partially nonhuman appearances). See Wikipedia or TV Tropes.

Nikkei Short for Nihon Keizai Shimbun, a financial newspaper in Japan, which measures the Nikkei 225. See Wikipedia or Everything2. (Also people who have emigrated from Japan, or people of Japanese descent. See people page.)

Nikkei 225 An index of the leading stocks traded on the Tokyo Stock Exchange. See Wikipedia or Everything2.

Takuhai Home delivery. (Also the former name of Tokyopop's Manga Magazine.)

Tareme Drooping eyes. I guess it usually refers to a style of anime or manga in which the characters (usually female) have such eyes (but perhaps might be used to refer to some real people's eyes, as well, I'm not sure). It's a look that connotes such things as sadness or innocence. Very child-like and cute, but is also sometimes associated with hentai (see sexual terms page; discretion advised). See TV Tropes or Everything2.

Terebi is the Japanese approximation of the word "television."

Uzumaki can mean "whirlpool" or "spiral shape." For example, the swirl pattern inside kamaboko or narutomaki (see food page). It's also the last name of the title character in the anime "Naruto" (The name Naruto Uzumaki is a reference to the sliced fishcakes with a spiral pattern). "Uzumaki" is also the name of a J-horror movie involving spirals.

Yuutsu Depression, melancholy. I mention this word here because it's in the Japanese title of the anime "The Melancholy of Haruhi Suzumiya" (Suzumiya Haruhi no Yuutsu). And I suppose it could be in other anime, too. Or whatever.
